Force an evolutionary trait of upward growth, then with every 100th generation or so, move the nutrient source just a very short distance along a steep logarithmic curve. Force the mycelium to grow like a tree, and then force it to traverse horizontally.
Eventually, over my guess is about twelve million generations or so, you'll have a mycelium stalk that grows upward and wanders along a mobile growth base platform, using spore cap 'feelers' that respond to the pressure and nutrients of a specific type of nutrient source.
It'd kinda look like a slow moving interior to one of those touchy glassy thingies with the plasma and the purple and the electrical conductivity
It would probably
I have no biology experience but I want to try breeding simple organisms to see if I can get interesting traits

>every 100th generation or so make a slight tweak
That's a lame way to do it.
Active competition would encourage it better.
